TIRE-BOLTING- MACHINE.

Application filed July 8, 1914. Serial N 0. 849,756.

To all whom it may concern Be it known that I, BENJAMIN F. MGCUL- LOUGH,a citizen of the United States, residing at Teague, in the county ofFreestone and State of Texas, have invented a new and usefulTire-Bolting Machine, of which the following is a specification.

The present invention appertains to wheelwright machines, and relatesmore particularly to an apparatus for applying and removing the bolts toand from the felly and tire of buggy, wagon and other vehicle wheels.

This invention contemplates the provision of an apparatus of the natureindicated, embodying a unique assemblage of component parts, to enhancethe utility of the structure,

and the apparatus being improved generally to increase the efficiencythereof.

With the foregoing and other objects in view which. will appear as, thedescription proceeds, the invention resides in the combination andarrangement of parts and .in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed Without departing from the spirit of theinvention.

The invention has been illustrated in its preferred embodiment in theaccompanying drawing, wherein:

Figure 1 is a plan view of the improved apparatus. Fig. 2 is a sideelevation there of. Fig. 3 is an enlarged longitudinal section of theapparatus, the section being taken approximately on the line 33 of Fig.1, parts being broken off or omitted. Fig". i is a cross section takenon the line 4-4: of Fig.3. Fig. 5 is a sectional detail takenapproximately on the line 5-5 of Fig. 3. V v

The present apparatus embodies a frame 1 constituting a suitable base 2having a pair of longitudinally spaced standards or up rights 3 and 4which carry a casting or yoke 5 at their upper ends. The casting or yoke5 is provided at one end, above the standard l with an upstandingbearing6. p

'Journaled through the bearing .6, is a 10in gitudinally arrangedtubular stock or sleeve 7 for holding the wrench and, drill hereinafterreferred to. One end of the tubular stock 7 is provided with an annularoutturned flange 8 and a sprocket wheel 9 is Specification of LettersPatent.

Patented May 4, 1915.

sprocket wheel 9, and around a lower and.

larger sprocket wheel 11 which is keyed or secured upon a longitudinaldriving shaft 12 journaled through the standards 3 and a below thecasting or yoke 5. That end of the shaft 12 which protrudes beyond thestandard 3 has secured thereon, a fly wheel 13 which is equipped with acrank handle 14; for conveniently rotating the shaft 12 man ua'lly,although the same may be operated mechanically, if desired. It isevident at this. point, that the rotation of the driving shaft 12 willimpart a rotary movement of higher ratio to the stock or sleeve 7 forthe intended purposes which will hereinafter appear.

Fitted snugly within that end of the stock 7 having a flange 8, is awrench 15 having a nut socket or bore 16 therein for the receptionandpassage of the nuts, and a set screw 17 is threaded through the flangedend 8 of the stock 7 to bind or clamp the wrench member 15 in place. Acollar or ring 18 is secured upon the other end of the stock 7, andbears or seats against the bearing 6, to retain the stock in operativeposition, and to prevent the longitudinal movement of the stock and sothat when the collar 18 is released, it will enable the stock to beremoved or withdrawn from the bearing. The last mentioned end of thestock 7 is also equipped with an inner bayonet slot 19 for the purposewhich will presently appear.

A removable drill chuck 20 fits snugly within that end of the stock 7remote from the end carrying the wrench member 15, and the said chuck 20is provided with a lug or pin 22 arranged to engage within the bayonetslot 19 of the stock 7 to hold the chuck 20 in place and to cause thechuck to be r0- tated with'the stock. The chuck 20 is bored or socketedto receive thebutt end of a drill bit 23, and the outer end portion of.the chuck 20 carries a set screw 24: for binding or clampingthe drillbit in place.

A clamp member is adjustably mounted upon the casting or yoke 5, andembodies a base 25 seated slidably upon the casting or yoke 5, andhaving an upturned jaw 26 at that endnearest the stock 7, the jaw 26being equipped with an upwardly opening recess 27 The said end of thebase 25 is also pro- 29 is restrained against longitudinal movesnuglywithin the longitudinal slot 28*" provided in the casting or yoke 5, anda feed or adjusting-screw'29 is journaled through that end of thecasting or yoke 5 having the bearing 6, and is threadedly engagedthrough the lower portion of the car 28. The screw ment, and may rotatereadily, to slide the clamp member longitudinally, and that end of thescrew 29 which projects beyond the bearing 6, is equipped with asuitable hand wheel 30 for facilitating the rotationjof the screw. Adepending clamping bolt 31 is threadedly engaged to the other end of thebase 25, and works within the longitudinal slot 32 provided in the yokeor casting 5, the head of the bolt 31 projecting below the slot 32 forassisting in clamping the base 25 of the clamp member upon the yoke orcasting 5.

The invention also embodiesa bolt holding device, which includes anupstanding fork 33. having its shank 34 journaled' or pivotally engagedto or through the casting or yoke5, and a screw 35 is engaged slidablythrough the arms of the fork 33 .at right angles with the fork, and ahand wheel36 is disposed snugly between the arms of the fork and isthreaded upon the screw 35. Thus, the screw 35 is restrained forlongitudinal movement, through the fork 33, and the wheel 36 isrestrained forrotary movement, in order'that when the hand wheel isrotated, the screw 35 will bemoved longitudinally as desired. Alever 37is fulcrumed to the shank of the screw 35, and is equipped adjacent itsfulcrum, with a bit 38 for engaging the kerf of the head of a tire bolt.

The present apparatus employs a crane or carrier 39, for supporting andmanipulating the wheel which is being operated upon. The crane 39includes a horizontal beam 40 having a slotted casting 41 bolted orotherwise secured to one end thereof and pivf otally engaged overapintle or bearing 42 Securedtothe standard of the frame 1. An inclinedbase 43 has'its upper end secured to "the free end portion of the beam40 and has its lower end pivotally engaged to a bearing member 44attached to the lower end portion of the standard 4. The beam 40' isthus capable of being swung in a horizontal plane toward one "Side orthe other of'the frame 1. The crane or carrier 39 may be held at variousangular positions, by means of a brace or adjusting bar 45 pivoted ,tothe free end of the beam 40, andhaving a series of lower notches 46adjacent its free end, which notches are engageable over an outstandingarm or bracket 47 rigidly secured to the standard-4. Thus,by disengagingthe brace or bar 45 from the arm or bracket 47, the crane may be swungto the position desired, and by engaging the proper notch 46 of thebrace or bar 45 over the bracket 47, the crane may be held in theposition to which it has been swung.v Y

The beam 40 carries a slide 48 which is capable of rectilinear or'reciprocatory movements upon the beam, and the slide 48 is equippedwith an upstanding spindle 49 for the engagement thereover of the wheelhub.

Adjustable wheelsupporting means is provided, and embodies a lever 50fulcrumed to one side of the slide 48, and a bar 51 having its lower endpivoted to the lever 50' and provided at its free or upper end with ahub seat 52loosely embracing the spindle49 and adapted to carry the hubof the wheel. The said side of the slide 48 is provided with an arcuateseries of notches or sockets 53 into which is engageable, a peg or pin54 for holding the lever 50 at various adjusted positions, to therebysupport the hub seat 52 at variousvertical positions, as desired.

7 An actuating rod 55 for the slide 48 is disposed immediately above thebeam 40 and'is engaged slidably through the slide 48, and

the inner end of the rod 55 is linked to a bell crank lever 56 fulcrumedwithin the casting a The slide 48 carries a set screw 56 for clampingthe rod 55 in position relative to the slide, and whereby the slide maybe adjusted longitudinally relative to the rod according to the variouscircumstances. A rod or link 57 has its upper end attached to the lever56 and has its lower end connected to a treadle 59 by means of a strip57". The treadle is fulcrumed to the base and is raised by a spring 58,and the lower end of the strip 57? is pivoted to the treadle. The lowerend of the link 57 is engaged through the upper angular end of the strip57 and adjusting nuts 57 are threaded upon the lower end of the saidlink. This treadle 59 when depressed, will draw the link 57 down wardly,to thereby draw the rod 55 inwardly or toward the fulcrum of the cranebeam 40,

and consequently, the slide 48 will be moved proper horizontal plane.The ,slide 48 is also adjusted longitudinally along the beam 40 and withrespect to the rod 55, by loosen-' ing the set screw 56, in order thatthe wheel felly or rim will have its inner side resting against the jaw26. The base25 of the clamp member is adjusted relative to the bearing6, in order that the recess or opening 27 will receive the wrench member15, and thereby thewrench member may project through the jaw 26 toengage the corresponding nut of the wheel when the bolt is beingtightened or loosened. It will be observed that the base 25 of the clampmember may be readily adjusted through the medium of the adjusting screw29 to properly position the jaw 26.. Then, by depressing the treadle 59,which will cause the slide 48 to move toward the standard 4, the fellyor rim and tire of the wheel may be moved away from the jaw 26 andwrench member 15, to enable the bolt to be readily inserted through theopenings of the felly and tire, and whereby the nut may be threaded uponthe inner end of the bolt. lVhen the operator releases the treadle 59,the spring 58 will return the slide to normal position, to bring thefelly of the wheel against the jaw 26 and into coiiperative relationwith the stock 7, the nut-being received by the socket 16 of thewrenchmember 15. The bolt may then beheld against rotation, by manipulatingthe lever 37 properly to engage the bit 38 with the kerf of the head ofthe bolt. By pressing the lever 37 toward the wheel, the bolt will notonly be held against rotation, but the felly will be clamped between thelever 37 and the jaw 26. Then, by rotating the shaft 12, the stock 7,and wrench member 15 carried thereby, may be rotated for tightening thenut, or conversely, when the nut is to be removed, the shaft 12 may berotated in the opposite direction to this end. By releasing the lever37, the bolt and wheel felly will be released, and the wheel may then bereset for applying the next succeeding bolt.

It is to be noted that the screw 35 which carries the lever 37 may beadjusted axially, by rotating the hand wheel or nut 36, and the fork maybe swung, in order that the lever 37 may be properly positioned andmanipulated for engaging and holding the bolt. The lever 37 may thus beadjusted and moved in various directions.

In case the bolt holes are irregular and r not radial to the wheel, thewheel may be adjusted to one side or the other of the longitudinalmedian plane of the machine, by manipulating the brace or bar 45 asabove described, in order that the bolt holes may be brought inalinement with the wrench as to hold the wheel felly and tire adj acentvthe drill bit 23, so that when the treadle 59 is depressed by theoperator, the wheel felly and tire will be moved into engagement withthe drill, bit, it being noted that the drill 'bit may be readilyrotated during the movement of the wheel felly and tire over the same.

The present apparatus may be adjusted for various sizes of wheels, andis otherwise of advantage as will be apparent to the wheelwright orpersons skilled in the art.

Having thus described the invention, what is claimed as new is:

1. Ina wheelwright machine, a frame, a jaw carried thereby for theseating of a wheel felly thereagainst, an upstanding fork having a shankjournaled to the frame, a screw slidable through the arms of the fork, anut threaded upon the screw and disposed snugly between the arms of thefork, and a lever fulcrumed to the screw .and havin a bolt-en a inelement.

2. In a wheelwright machine, a frame, a rotatable wrench member carriedthereby, a clamp member including a base slidable upon the frame, thebase having a jaw at one end provided with an opening for the receptionof the wrench member, and having an ear at the said end slidable throughthe frame, an adjusting screw carried by the frame and threaded throughthe said ear, a clamping element carried by the other end of the saidbase and slidably engaging the frame, and bolt holding means carried bythe frame and cooperating with the said jaw and wrench member.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
